Detailed description of the invention

Below in conjunction with embodiment, this utility model is described in further details:

As it is shown in figure 1, roll 3 is for the needs cooled down, some along processing axial hole, the edge 3-1 of body of roll 3-2；In three adjacent axial hole 3-1, the short oblique hole of two communicated need to be bored in the aperture of two axial hole 3-1 on both sides, and a long oblique hole need to be bored in the aperture of a middle axial hole 3-1.

As in figure 2 it is shown, for boring convenient in the axial hole 3-1 of roll 3, design is processed oblique hole special fixture in roll axial hole, is vertically fixed on the locating dowel 2 on chuck body 1 bottom surface 1-1 including chuck body 1 and one end；Locating dowel 2 other end inserts roll 3 axial hole 3-1, and the exit end face of axial hole 3-1 is adjacent to the ground 1-1 of chuck body 1, under the common restriction of locating dowel 2 and bottom surface 1-1, by this utility model axial restraint.

As shown in Figure 2, chuck body 1 is included on chuck body 1 bottom surface 1-1 the arc locating surface 1-2 of the body of roll 3-2 edge flush with roll 3, lengthwise position of the present utility model is fixed by arc locating surface 1-2 by being in close contact with roll, makes this utility model not rotate in the 3-1 of axial hole；Chuck body 1 is additionally included in the internal oblique hole 4 with the angled setting of locating dowel 2 of chuck body 1, oblique hole 4 and locating dowel 2 intersect at the contact surface of locating dowel 2 and bottom surface 1-1, and oblique hole 4 passes locating dowel 2 in locating dowel 2 side, described oblique hole 4 other end passes chuck body 1 inclined top face 1-3, the drill bit limited for boring by the diameter range in oblique hole 4 is swung back and forth, and is positioned accurately by the drill bit being used for boring in the exit position of locating dowel 2 side by oblique hole 4.

As shown in Figure 2, Figure 3, Figure 4, inclined top face 1-3 is vertical with oblique hole 4, and this utility model can be made to facilitate processing.

As shown in Figure 2, Figure 3, Figure 4, the oblique hole 4 of chuck body 1 includes three kinds, the most oblique hole I 4-1, oblique hole II 4-2 and oblique hole III 4-3.

As in figure 2 it is shown, oblique hole I 4-1 becomes the angle of 30 ° to arrange in the plane that locating dowel 2 centrage is constituted with roll 3 centrage and with locating dowel 2, carry out growing the boring in oblique hole for stretching into drill bit.

As shown in Fig. 3, Fig. 4, Fig. 5, in 40 ° of angles and oblique hole II 4-2 and oblique hole III 4-3 mutually constitutes the angle setting of 70 °, for stretching into the boring in the short oblique hole that drill bit carries out communicating on roll 3 to oblique hole II 4-2 and oblique hole III 4-3 with locating dowel 2 respectively.

For the drill bit deep enough oblique hole 4 of energy of boring and it is unlikely to produce big rocking in oblique hole 4 for convenience, designs the internal diameter in oblique hole 4 more than the 0～2mm of bit diameter.

As shown in Figure 2, Figure 3, Figure 4, arc locating surface 1-2 includes two sides, wherein intrados is concordant with the body of roll 3-2 internal ring edge of roll 3, be adjacent to the roll neck of roll 3, the body of roll 3-2 outer annular edge of the extrados in arc locating surface 1-2 and roll 3 is along concordant, limited the radial position of chuck body 1 by two sides arc locating surface 1-2, make this utility model location when boring oblique hole more accurate.

Radial displacement in locating dowel 2 can extend into axial hole 3-1 for convenience and in the 3-1 of axial hole is unlikely to produce big impact, and the diameter of Design Orientation post 2 is less than the 0～2mm of axial hole 3-1 internal diameter.

Processing for convenience, chuck body 1 of the present utility model is one-body molded with locating dowel 2, and using between the one-body molded locating dowel 2 produced and the bottom surface 1-1 of chuck body 1 is the right-angle relationship being directly transited into, and more can facilitate the location of locating dowel 2.

Using method:

Oblique hole is bored in roll 3 axial hole 3-1, first the chuck body 1 matched with oblique hole is selected, fit relative with the axle journal of roll 3 for the intrados of arc locating surface 1-2, in locating dowel 2 is stretched into axial hole 3-1 and make the bottom surface 1-1 of chuck body 1 be adjacent to roll 3 axial hole 3-1 exit end face, the most just this utility model has been positioned, the drill bit being used for boring is stretched in the oblique hole 4 of chuck body 1, under the restriction in oblique hole 4, drill bit for boring will not occur to swing and shift phenomenon, completes the boring work in oblique hole the most accurately.
